BMW 325d Parts & Accessories

The BMW 325d uses the M57 3.0-liter twin-turbodiesel inline-six, making it one of the most potent diesel variants in the E90 3 Series range. With 197 hp and 400 Nm of torque in standard form, the 325d combines sports car performance with diesel economy, and it responds exceptionally well to aftermarket upgrades targeting both power and handling.

Popular Upgrades

An ECU remap on the M57 twin-turbo is one of the most effective upgrades available for the 325d, typically pushing output to 240-260 hp and 500-540 Nm with Stage 1 hardware. Performance air intakes and decat downpipes further improve turbo response and sound, while coilover suspension and sway bar upgrades sharpen the E90 sedan's chassis dynamics significantly.

How much power can the BMW 325d M57 make with tuning?

The stock M57D30TU2 produces 197 hp and 400 Nm. A Stage 1 remap typically yields 230-250 hp and 480-520 Nm. Stage 2 builds with intercooler and intake upgrades can reach 270-290 hp and 560+ Nm while remaining reliable with regular oil changes and quality diesel fuel.

What suspension upgrades work for a BMW 325d E90?

The 325d's slightly higher kerb weight versus the petrol variants means coilover spring rates should account for the M57 diesel's extra mass. Sport-spec coilovers designed for the E90 range handle this well. Adding an upgraded front sway bar and rear anti-roll bar significantly reduces body roll on both road and track.
